Weird Mozilla error

[Julian Jares]

Hi:

I've just installed Mozilla 0.9.5 today, and I'm having a weird issue
Error description:
When I logging to Imp, all other applications, except imp, get logged in, so I
can see horde info, turba info, and kronolith info, but I cannot see imp's.
message log show a correct signon to the mail server... imp.log shows a success
login and then a failed [info]
When I toy around for a while with the security settings I manage to login, but
then I close mozilla and try again and Im out again... I know its either
something with cookies, mozilla's auto-form-saving feature or caches.
Also, I discarded cache based on seeing the actual headers.
The only workaround I found was not allowing mozilla save cookies for
webmail.jares.com.ar (that's my horde site)

Anyone seen anything like this?

Thanks
